We also support "custom guitools" in git-cola using this same
mechanism.  If this gets accepted then we'll want to make
similar change there.

There's always a small risk that user-defined tools can conflict
with builtin shortcuts, but otherwise this seems like a pretty
nice feature.  Curious, what is the behavior in the event of a
conflict?  Do the builtins win?  IIRC, Qt handles this by
disabling the shortcut and warning that it's ambiguous.

Please documentation guitool.<name>.accellerator[-label] in
Documentation/config.txt otherwise users will not know that it
exists.

It would also be good for the docs to clarify what the
accelerators look like in case we need to munge them when making
it work in cola via Qt, which has its own mechanism for
associating actions with shortcuts.  Documented examples with
one and two modifier keys would be helpful.


cheers,
